EMGA-921

Hydrogen Analyzer

This is an hydrogen elemental analyzer with high accuracy and repeatability suiting to cutting-edge technology's R&D as well as quality control in the market of steel, new materials, catalyst and so on. This is a new generation model optimized to fit to user's requests.

Principle and Gas flow diagram

The sample is placed in a graphite crucible and the crucible is maintained between the upper and the lower electrode of the impulse furnace. A high current power passes through the crucible to create a high temperature.

The oxide in the sample reacts with the graphite crucible, and is extracted as carbon monoxide (CO), and carried together with the carrier gas. The extracted gas is directly analysed after the dust filter. According to the oxygen concentration, it is determined by CO or CO2 after pass throw oxidizer (Copper Oxide) with a non dispersive Infra-Red analyser (NDIR).

The Hydrogen is determined with a non dispersive Infra Red analyser as H2O after H2 passes through the oxidizer (Copper Oxide).

The Nitrogen in the sample is extracted as nitrogen gas (N2) and its concentration is determined by a thermal conductivity detector (TCD).

User-friendly Software

Measurement Window

Extracted gas signals are displayed in real time numerically and also as curves together with temperature level. Graphs are saved automatically.

In the measurement window, sample weight can be registered automatically. Results are saved in a data table for easy management.

HORIBA originality-Maintenance navigator

Maintenance counter informs users at the timing of consumables replacement to keep high accuracy means. And as navigator describes the easy to understand procedure for the replacing parts, operator can do maintenance works with absolutely no experience and technical knowledge.
